Antibiogram of methicillin resistant Staphylococcus aureus (MRSA) of animal origin from Chhattisgarh

Abstract

Present investigation was made to study antibiogram profile of Methicillin Resistant Staphylococcus aureus (MRSA) of animal origin. MRSA isolates were obtained from bovine mastitis and wound infection of animals using cultural isolation and were confirmed by S. aureus specific thermonuclease (nuc) and MRSA specific mecA gene in PCR assay. A total of 13 MRSA isolates were obtained and subjected to antibiotic sensitivity test using 10 numbers of selected antibiotics by disc diffusion test. MRSA isolates exhibited variable degree of sensitivity towards various antibiotics. MRSA isolates were detected 100% senisitive to linezolid and imipenem followed by clindamycin (92.31%), tetracycline (76.92%), vancomycin and gentamycin (53.85%). Isolates showed higher rate of resistance towards amoxicillin (84.62%) and penicillin (76.92%). All the isolates were found resistant to cefoxitin and methicillin. It can be concluded from present study that isolates harbouring mecA/ MRSA gene have tendency to exhibit resistant towards multidrug and treatment option can be explored by studying antibiogram of MRSA of particular region.

Methanolic extract of Hemidesmus indicus root augments the antibacterial and antibiofilm activity of amoxicillin and clindamycin against methicillin-resistant Staphylococcus aureus of bovine origin

“…Furthermore, PCR produced the desired amplicon size of the S. aureus-specific nuc gene (270 bp) and the MRSA-specific mecA gene (533 bp). Sannat et al (2021) previously reported that these isolates were almost completely resistant to methicillin, cefoxitin and amoxicillin, but sensitive to linezolid, imipenem, clindamycin and tetracycline.…”

Efficiency of Pyroligneous Extract from Jurema Preta (Mimosa tenuiflora [Willd.] Poiret) as an Antiseptic in Cats (Felis catus) Subjected to Ovariosalpingohysterectomy

“…Infectious wounds are common in surgeries such as ovariosalpingohysterectomy, and this is made more problematic in the presence of multidrug-resistant bacteria, such as S. aureus . Resistance to beta-lactams is common and is often due to the presence of genes such as blaZ and mecA [ 17 ]. Therefore, herbal medicines have emerged as potential alternative antiseptics.…”
